Baton Rouge Metropolitan Airport (IATA: BTR, ICAO: KBTR, FAA LID: BTR), also known as Ryan Field, is a public use airport located four nautical miles (7 km) north of the central business district of Baton Rouge, a city in East Baton Rouge Parish, Louisiana, United States.
The airport was originally Harding Army Air Field during World War II and was used by the United States Army Air Forces Technical Service Command as a maintenance and supply base.
Today other than the runways, virtually no traces remain of the military installation.
It has an okay rendition of the KBTR terminal, but runway 13-31 is not properly signaled and has "X" from the days the runway was being worked on. The passenger gates do not work and the gate markings are wrong. I reported it to the developer, but he may have not had time to work on it to fix it.
